Numbers and Operations

Unit Description:

This unit is a review of the concepts of rational numbers with an emphasis on operations involving negative numbers, along with graphing in the coordinate plane. Students will also review writing numbers in exponential and standard form.

Big Ideas:

• Variables represent unknown quantities and are used in algebraic expressions.
• The order of operations is necessary when evaluating expressions.
• The absolute value of a number is the distance a number is from zero on a number line.
• Numbers increase in value as you move to the right on the number line and numbers decrease in value as you move to the left.
• Both positive and negative numbers can be represented on a coordinate plane.
• Opposites have a sum of zero.

Essential Questions:

• How do negative and positive numbers help in describing real world situations?
• How can you use numbers and symbols to represent mathematical ideas?
• What happens when you add, subtract, multiply and divide integers?
